During his visit to the Battle of Britain Bunker museum in Uxbridge on Friday, March 16 accompanied by his Polish counterpart, Jacek Czaputowicz, Boris Johnson spoke of the role Russia played in the poisoning of Sergei Skripal in Salisbury.
"Our quarrel is with Putin's Kremlin, and with his decision, and we think it overwhelmingly likely that it was his decision to direct the use of a nerve agent on the streets of the UK, on the streets of Europe, for the first time since the Second World War. That is why we are at odds with Russia."
Questions over Johnson's evidence behind the strong statement poured into commentary sections on Twitter, casting shadow on its credibility.
